In an experiment the traditional mode of voice communication between air traffic controllers and pilots (a vocal and auditory task) was compared with a data-link mode (a visual and manual task). Eight subjects controlled air traffic, both via voice channels and via data-link in a laboratory simulation. Mental workload was assessed through performance, heart rate variability and subjective judgment. The results pointed in the direction of a higher mental workload in the data-link mode than in the voice communication mode. The difference in workload could be attributed to a redistribution of the required cognitive resources.
